WebSep 12, 2024 · Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in … WebA chemical reaction is said to be exothermic when it releases energy in the form of heat. The system (reaction) releases heat to the surroundings as the reactants transform into products. For example, the burning of wood releases heat. An exothermic reaction causes the surroundings to heat up. how did people take baths in ancient times
